A student was critically injured Friday after a gunman opened fire at a high school in suburban Denver, Colo., before apparently killing himself.
Authorities say that
the suspect, who's been identified as 18-year-old Karl Pierson, was a student at the school, Arapahoe High School, which is located in Centennial. He had reportedly sought to confront a teacher.
The victim, a 15-year-old female student, remains in critical condition
after suffering a gunshot wound. The victim's identity has not been released.
Earlier, Colorado emergency officials said police responded to a report of a shooting at Arapahoe High School. Police were outside the school, and students were seen milling around on sidewalks.
The school is about eight miles east of Columbine High School in Littleton, where two teenage shooters killed 12 classmates and a teacher before killing themselves in 1999.
The latest school shooting comes almost one year
since the tragedy in Newtown, Conn., where 20 first-graders and six educators were killed.
